leva [86]
Area of a triangle = \pi r^{2}
r = diameter/2
so area = pi * (13/2)^2
= 3.14*6.5*6.5 = 132.665

Harry reads equal numbers of pages of a book every week. The graph shows the number of pages of the book left to read, y, after
horsena [70]

Answer:

  • y=-55x+275

Explanation:

The given points are:

  • (0, 275)
  • (1, 220)
  • (2, 165)
  • (3, 110)
  • (4,55)
  • (5, 0)

Since a <em>straight line joins</em> all the points, the equation that models the <em>relationship</em> is linear and you can find the slope-intercept equation which has the general form:

             y=mx+b

Where:

             m  is the slope

             b  is the y-intercept

<u>1. Find the slope</u>

You can use any two ordered pairs.

  • m = rise/run = Δy/Δx = [220 - 275] /[1 - 0] = - 55

<u>2. Find the y-intercept</u>

The y-intercept is the value of y when x = 0; thus it is 275.

  • b = 275

<u>3. Substitute in the slope-intercept equation</u>

  • y=-55x+275

That is the last option.
